Answer:
Solution for If f(x) = 2x – 6 and g(x) = x – 2x2, find each value. f(2)
The required value of each function is
f(h + 9) = 2(h + 6)
g(h + 9) = -(2h + 19)(h - 9)
What is a function?In mathematics, a function from a set X to a set Y assigns to each element of X exactly one element of Y.
Now the given functions are,
f(x) = 2x – 6
g(x) = x – 2x²
Now putting x = h + 9 in f(x) and g(x)we get,
f(h + 9) = 2(h + 9) – 6
⇒ f(h + 9) = 2h + 18 – 6
⇒ f(h + 9) = 2h + 12
⇒ f(h + 9) = 2(h + 6)
and
g(h + 9) = (h + 9) – 2(h + 9)²
⇒ g(h + 9) = h + 9 – 2(h² + 81 + 18h)
⇒ g(h + 9) = h + 9 – 2h² + 162 + 36h
⇒ g(h + 9) = -2h² + 37h + 171
⇒ g(h + 9) = -(2h + 19)(h - 9)
Thus, the required value of each function is
f(h + 9) = 2(h + 6)
g(h + 9) = -(2h + 19)(h - 9)

The length of each side of a cube is x + 1 inches. What is the volume of the cube in cubic inches?
Answer:
V = x³ + 3x² + 3x + 1 in³
Step-by-step explanation:
The volume (V) of a cube is calculated as
V = s³ ( where s is the side ) , then
V = (x + 1)³
= (x + 1)(x + 1)(x + 1) ← expand second pair using FOIL
= (x + 1)(x² + 2x + 1) ← distribute
= x³ + 2x² + x + x² + 2x + 1 ← collect like terms
= x³ + 3x² + 3x + 1

f(x)=x^2-2x+3 g(x)=x^2-2x-4 Find f(g(-2)
Answer:
[tex]f(g(-2))=11[/tex]
Step-by-step explanation:
We are given the two functions:
[tex]f(x)=x^2-2x+3\text{ and } g(x)=x^2-2x-4[/tex]
And we want to find:
[tex]f(g(-2))[/tex]
We will find g(-2) first. So:
[tex]g(-2)=(-2)^2-2(-2)-4=4+4-4=4[/tex]
Thus:
[tex]f(g(-2))=f(4)[/tex]
Evaluate:
[tex]f(4)=(4)^2-2(4)+3=16-8+3=11[/tex]
Therefore:
[tex]f(g(-2))=11[/tex]
